2 points Mr Birla.
1st this decibel meter reading to be captured from the driver seat with all windows closed.
2nd How will this impact the engine temperature??
Birlaji during first 2 tests the cooling fan was running but at final test (silver colour sheet) the cooling fan was off (as AC was off) that's why the reading was low😅
Bro, in last test (moco) there is no person in driver seat. Please follow exact same procedure while testing all scenarios. Otherwise people lose their trust slowly.
Yes, i am thinking the same.
Even, i thought the same..
Olunga video paruya on that time engine was running
@@saravanang2513😂 Engine run pannaama noise varaadhu bro.. i know.. im telling about acceleration... Noise will be higher if you accelerate the engine.
Yess...i too thought the same.. moco damping pannum podhu engine rev panavae ila...so repeat the video
Have anyone noticed the trick????? When measuring decibel value for “without insulation “ and “partial insulation” the driver was inside the car cabin for acceleration to get high and low decibel value….but when measuring decibel value for “last test“ the driver was not inside the car cabin for acceleration so we can only measure low decibel value…I guess mr.Birla is promoting car sense…. @Birlas Parvati can u clarify this ??
April Fool video 😃
Ofcourse yes ... He is simply promoting that.... Oru nalla youtuber nu Ivar video paatha... Last la ivarum kaasukaaga junk product videos podraaru... Money makes everything...
I also noticed. Thank u
Above everything .. 5 db difference is not a very much difference when it comes to noise and reduction ratio...
Sir been ur fan from long time have learnt a lot from you, its better to avoid these kind of product videos, instead do a generic review of all products without connecting with any shop.

As you said, 3 cylinder engine makes more noise and it evident inside the cabin but you tested outside the car, who’s gonna sit in the bonnet? After the insulation whether the sound transfer inside the cabin or not, you should have tested inside the cabin not outside the cabin sir.
Other glitch in installing this sheet is how the engine temperature maintained inside the engine bay? How it’s maintaining the temperature inside the engine bay whether it’s increasing the temperature inside the engine bay or reducing after installing the thermo sheets ?
What we need is simple
1. Cabin insulation noise which means inside the car not outside the car
2. How well the engine heat it transfers inside the engine bay
Correct bro. Main purpose of insulation is reducing sound inside the car. But he never tested that.
For point number 2: shall we say that the controlled heat on one side can flow through the bottom and increases the temperature inside the cabin from the floor?
Hi Birla Bro,
Just 1 hour back, my friend was asking me about Sound Dampening for his Tata Tiago Diesel, today's video is about the same, I have shared your video to him...
Very informative...

This is not advisable. Heat dissipation will become poor.
What about engine sound inside the car
Yes I had same question
Remove engine then no sound bro
@@omgsab001 yes bro u r correct
Yes, I had same question bro
Yarra Neegalam😂😂😢
நல்ல விளக்கம். நான் 3M sound dampening பயன் படுத்தி கொண்டு இருக்கிறேன். நன்றாக உள்ளது....
Hi, what is the need or necessary for reducing this engine noise externally. Psl explain why it is needed?
Sound difference inside the cabin can also be tested before and after installation
Bro engine refinement aaga yethuna soluvinga nu partha.... Atha vida car cover pottutu start pannunga innum sound kammiya varum soluvinga pola
Bad advertisement, we don't want to see the addictive and gambling gaming advertisement. Pls avoid this add, then we will skip your videos.
I liked the subtitles 🙂
Appreciate the effort, but such experiments should happen in an ideal environment, without any external noise (too much noise in the background, so a sensitive device like decibel meter would capture everything), the min/max value should have been captured by revving the engine to a certain RPM in all three scenarios, and the readings should be taken externally and inside the cabin as well.
6K is overrated if the cabin is not good enough to arrest exterior noises, wind noise, tyre noise. May not make much difference.
These days I think petrol engine are way better tuned.... Diesel engines eh nalla refinement oda tha varuthu... So modern cars ku (mostly petrol) ithu avasiyam irukaathu nu thonuthu....
நீங்கள் கார் உள்ளே அமர்ந்து அதனுடைய சவுண்டும் சொல்லி இருந்தால் இன்னும் நன்றாக இருக்கும்
நம் பெரும்பாலும் கார் உள்ளே அமர்ந்து செல்லும் போது தான் அதிக சவுண்டை உணர்கிறோம்
I think insulation will block airflow so it's cause engine heating up, not recommended
காருக்கு உள்ளே ஒலி எவ்வளவு குறைகிறது என்பதுதான் முக்கியம் .. எனவே காரின் உள்ளே ஒலி அளவு எவ்வளவு குறைகிறது என்பதை அளவிட்டு கூறியிருந்தால் பயனுள்ளதாக இருந்திருக்கும் ...
Car cabin noice less ha irukura bujet friendly cars list video poduga thalaivare 🎉
Was the Engine in Higher Rev on the First and Second testing.. Looks like the engine is idling in Final Testing ..
This is an unwanted update to the car. You guys want to sell some unnecessary products that is not at all required for the car. What if the sound comes little more? It is not going to affect us in any way. The company itself has norms regards to the car sound and the car is already built accordingly. Don't promote these kind of irrelevant products please.
Well said... Moreover this sound insulation will not reduce that much of decibels. He did one trick. Hope you have noticed that.
Well said
Well sound treatment is already provided in high end luxury cars but in low end due to cost cutting they are absent 😢. Don't speak rubbish unless you don't know 😂
@@kingofmonsters7452 Sound treatment is not required is my point. Before commenting try to understand what is already written.Dont be so dumb.
Don’t talk shit if you don’t understand stuff.
Also let's know the cabin temparature before n after fixing it.
Does this have thermal insulation properties to bounce engine heat too?
Shall we say that the controlled heat on one part of the body flows through the bottom of the engine and increases the cabin temparature from the floor beneath.
Ur Presentation is beautiful subject to bonnet closing is peculias. Close bonnet slowly on lock than press it it vil lock or put same gress or vesline in lock .
Now a days only promotion videos uploaded., missing our driving videos 😢
7500 for the foam sheet? Which reduces sound by 15% on avg?? Too costly
Mr.Birla, you can try a TPMS from jk tyre TREEL, it's fixed to each tyre and sensors are attached/ linked to your mobile..no wiring required. Try and have your feedback.tc
Mr.Birla your views please.
Who cares about engine noise outside 😂😂😂 Birla , please calculate engine noise inside cabin - before and after bonnet work. I think thats gonna be your next content video for damping sheets on doors 😂😂😂
🔥🔥🔥வண்டியை கொழுத்தி விட்ருவாங்க போல..😂😂😂...
Bro, Check and show whether Engine cabin heat is increasing or decreasing with temperature device after this insulation. Obviously we know. Please avoid promotions like this.
Nice effect bro but what about inside cabin noise engine sound reduced?
Outside sound control agi no use...please don't support these kind of marketing
6000 rupees'ku effective ah irukura mari theriyala
Not required for 4-cylinder NA petrol engine
Why is there no one at the wheel revving the engine when you checked the moco sheet? Looks like a advertorial sponsored by moco
Does this sound proof is fire proof/heat control
Dont promote jugad products
Bro great. But whether this insulation sheet can withstand the heat davelopped in engine bay? If so what is the thermal resistance percentage as per the norms?
Shall we say that the controlled heat on one part of the body flows through the bottom of the engine and increases the cabin temparature from the floor beneath.
Why have you deleted the car suapension change video?
I enquired the cost for MOCO in the same shop. They are charging ₹7000. But it was said as ₹6200 in this video.
Bro Please make a video about inside noise. It will be useful for all.
என்னோட ஸ்விப்ட் காருக்கு after market சவுண்ட் ப்ரூபிங் பண்ண முடியுமாங்கற டவுட் கொஞ்ச நாள் முன்னாடிதான் வந்தது. அதுக்கான பதில் இன்னைக்கு கிடைச்சது. நன்றி!
Long time waiting for this video. Thank 5
Really good effort
@05:58 76 illa 77.8 which is 78..there is no difference
The whole point of insulation is to mitigate sound that enters inside the car. Why would you test with the db meter outside. There are environmental sounds that add to it. The radiatior fan was off on the third test. Please don’t be this inconsistent for the sake of promoting a store or a product. Stuff like this would only downgrade your channel more. Please be genuine.
How to reduce the Heat and Sound for car bonnet,any suggestions,which brand best material need to use.
In the last test the engine was idling and it’s obvious there’s no driver to rev the engine. The result is just not conclusive and not believable at all. And even in the second test the difference in decibel is negligible. I don’t think it’s safe to cover the entire under part of the hood like that, there might be safety concerns. Even cars from the factory, oem soundproofing will only be present in the middle portion of the underside of the hood. Rest portion will be left free. Very half baked promotional videos from you recently.
Well said
Cabin la noise difference iruka..athu tha v need
Will it help in reducing suspension thud noise inside the car if we insulate all doors and boot?
Only reduced 14% of noise is unnecessary… sometimes it may lead to rust formation in the hidden places of the bonnet. Instead doing this upgrade try to maintain your Vechile properly by changing lubes, filters, spark plugs every 10k or 1 year to keep your car running smoothly without any issues.
Did you remove the first sheet before applying the second? Or is it double dampened?
Yes, he removed it seems
Use sound deadning sheet on firewall n dash panel n bulk head on inner n out body) than c the differences.
பானட்க்கு மேல சவுண்டு வரலை ok ஆனா காருக்குள்ள எப்பவும் போல சவுண்ட் வருகிறது என்ஜின் ரூமுக்கும் கார் கேபினுக்கும் நடுவில் புது தடுப்பு எதுவும் நாம் வைக்காத
தால் எப்பவும் போலவே என்ஜின் சவுண்ட் வருகிறது நான் போட்டு ஒரு உபயோகமும் இல்லை. வேஸ்ட்.
காருக்கு வெளியே சவுண்ட வந்தால் என்ன வரலைன்னா என்ன?
சார் கொஞ்சம் யோசித்து பதிவு போடுங்க
Aprox 8 k total waste of money

Two material use that value 64
Bro water wash pannum bodu damage aaguma. And it is easily removable ah
Good Question. I also have the same doubt.
Should have shown the same experient from inside the cabin. How does it matter what's happening outside the car
Hi sir....are you from Virudhunagar???? Many videos have been shooted at virudhunagar...i am from Aruppukottai🥳

Sir we don't need this in Hyundai petrol engines. Its already like ev when you sit inside the cabin.
1st comment, great but music is missing brother
bro, car inside sound proof podalama
If you want music, watch a music video, why are you watching a program on cars and sound damping?
Hi sir
Birla ji I will give u my celerio ZDI car for ur experiment no need meter and all ..
Let me know if u r willing.
செம்ம bro
Can carpet be added on top of the sheet.. i think my car has only carpet ..
Super
Hi Birla sir,post ur audio system and music system owner ship review..I have buy the android music system from car sense Alandur branch..but if I saw ur review means that will be helpful for other who want to buy
How much ammount for innova
Sir Its fire proof?
Some help for sir
Your good advertiser for MOCO Brand, ஆனால் தலையில் இருக்கிற கொண்டைய மறந்து விட்டார்கள். First two test driver inside the cabin he was rise the acceleration. But last MOCO dummy sheet no driver inside and car engine running very slow ideal position. 🤣😂🤣😂😂🤣😂🤣😂
How about heat dissipation
You could have test the sound inside the car too ....
Bro, When you are going bye new car? If it is what would be ?
I guess it is Honda city new gen
Bro road noise and Tyre noise reduction ku edhu insulation iruka bro? Irundha video podunga
You have to try high end tyres like Michelin, continental. Because it has more silicone, tyre will be softer. So road noise will be reduced a lot. But life will be little less when compared to hard tyres.
@@aravindamk87 Thanks bro
@@sudhan152 if you're budget is less, better go with bridgestone (b290, sturdo) soft tyres. Comparatively less amount than Michelin. But you can't expect noise reduction like Michelin but 70% of sound will be reduced.
Who wants out side noise..... Need cabin noise only
Mg facelift review need bro
Nenga inside car check panni irukalam
Ethathu problme vanthuchu na engine la we can’t identify without sound while driving
don't encourage such 3 party product at all level, this make lead into wrong in term of OEM Policy and backfire to customer who invested lakhs.

Sir petrol vehicle no need of this item is it? But Diesel vehicle should place this one
Looks like Manipulated test.... Not expected

Waste of money
Who cares if the car makes noise on the outside !! I want to know how much the noise is reduced on the inside !!!
i10 & i20 is way quieter without insulation, with insulation imagine 😬
This is how refined engine behave❤
Avaru demo kaatunadhe i10 thaan😅😅
Yes that's true. Hyundai cars mostly be like ev when you sit inside
At last u tested without starting the engine bro which is totally incorrect.
2nd person...
No man,you r measuring sound above bonnet: what about cabin sound??? . There cannot be any change
Hi brother, I like your videos generally.
However, in this,
1. didn’t like the way you rounded off values in favour of damping sheets as if like promoting .. like e.g., 80.3 without damping you say its 81… with first damping, you say max value as 77 when it reads 77.8, and min value as 65 when it reads 65.5 🙄…
2. Also for final damping, since there was no driver, many like me would have got a doubt when was the car started
Humble request to try and show us experiments the same way you do before and after. Also be specific with values.
Yow cabin la noise korayuma
